HOT-WATER-OIRCULATING SYSTEM.

Specification of Letters Patent.

Patented April 14, 1908.

Application filed March 23, 1906. Serial No. 307,620.

To all whom it may concern:

Be it known that I, GEORGE A. TRIGGs, of Lake Park, Dickinson county, State of' lowa, have invented certainnew and useful lmprovements in Hot-Water-Circulating Systems, of which the following is a specification.

The object of this invention is to provide improved means for securing the circulation of hot water through pipes which supply it to the faucets in a residence for consumption for various uses. lith the usual arrangement of boilers for domestic use and the water circulation pipes connected therewith, the air which accumulates in the top of the boiler interferes with the circulation of the water and before hot Water is obtained at the faucet it is necessary to permit the water standing in the pipe, which will be cold, to run out.

By my invention a circulation of water through the pipes is constantly maintained; the back-flow of water from the bottom of the boiler to the faucet is prevented and as soon as the faucet is opened, a supply of hot water is obtained.

The invention consists generally in the constructions and combinations, hereinafter described and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification; Figure 1 is an elevation of a hot water system for domestic use embodying my invention. Fig. 2 is a vertical section of the controlling valve showing it in position for permitting a circulation of water through the pipes. Fig. 3 is a similar section showing it in position for checking the back-flow of water from the ipe leading to the lower part of the boiler. Fig. 4 is a detail of the valve.

ln the drawing, 2 represents a heater of any preferred kind. I have here shown an ordinary kitchen range.

3 represents a boiler of any preferred kind. l have here shown such a boiler as is generally used in connection with a kitchen range for heating water for domestic use.

4 represents a suitable fixture such as a kitchen sink. f 1

13 represents a pipe for supplying cold Water to the circulating system. This pipe is also preferably provided with the faucet 11 arranged in connection with the sink 4. Connected to the pipe 13 is a pipe 6 which enters the top of the boiler and extends to a point near the lower end thereof and thereby supplies cold water to the lower part of the boiler. A pipe 9 leads from the top of the boiler'to a point near the sink 4 where it is connected toa pipe 15 which is connected at one end to the pipe 8 and at its opposite end to the pipe 16. The pipe 8 leads to the heater 2 and may be connected therewith in any preferred manner as by an ordinary water-back. From the heater 2 a pipe 7 leads to the boiler and a branch pipe 14 from the bottom of the boiler connects with the pipe 8 at a point between the sink and the heater.

A valve disk 17 is provided in the pipe 15 below the connection with the pipe 9 and is connected with a disk 18 above the pipe 9 by a rod 19. The valve 17 has a seat 2O and a cylinder 21 is attached to the disk 18 and is provided with a series of openings 22 beneath said disk. The disk 18 and the cylinder 21 forni a piston or plunger for operating the valve 17. A coupling 23 is provided between the pipe 15 and the pipe 16 and has a chamber into which the disk 18 is moved when the Valve 17 is closed. When the valve 17 is openthe disk 18 will drop into the end of the pipe 15 and the openings 22 in the wall of the cylinder 21 will be closed and the passage of water` therethrough prevented.

When the parts are in the position shown in Fig. 2 of the drawings, the lower disk is oif from its seat and communication is had between the pipes 9 and 8 and a constant circulation will be maintained from the top of the boiler through the pipe 9, the valve 15, the pipe 8, the heater, the pipe 7, and the boiler. There will also be some water passing out of the lower part of the boiler through the branch'pipe 14 into the pipe 8. As soon as the faucet 10 is opened and the pressure on top of the disk 18 is relieved, the ressure of water in the pipe 9 and in the bo y of the valve 15 will move the valve upward, thereby bringing the disk 17 against the seat 20 and causing the disk 18 to move upward above the end of the valve body and into the enlarged chamber formed by the coupling 23. The water will now pass freely from the pipe 9 into the pipe 16 and to the faucet, while the valve disk 17 being brought against its seat, the water in the pipe 8 and in the lower art of the boiler cannot flow through the va ve body. There is, therefore, now a free low of water from the top of the boiler 8 directly to the faucet 10 through the pipe 9 and the pipe 16 and the back flow of water from the pipe 8 is prevented. The disk serves to close the passage leading to the pipe 16 and prevents an` accumulation of cold water in said pipe when the faucet is closed. The use of the disk 18 enables me to place the faucet at a considerable distance therefrom and still obtain a supply of hot water immediately after the opening of the faucet, as the closing of the disk 17 will direct the water from the pipe 9 up past the disk 18 and through the pipe 16 to the faucet.

By this construction any air that accumulates in the top of the boiler will be permitted to escape through the faucet 10 whenever said faucet is open and therefore the circulation of water through the pipes 9 and 8 will be constant as it will never be interfered With by such accumulation of air. Moreover, as there is a constant circulation of water through the pipes 9 and 8, this water will be always hot and as soon as the faucet 10 is opened, hot water will at once be obtained without waiting 'for the water in the pi e to first run off as is the case with the usua systems employed for domestic service.

It will be understood that this system can be applied in connection with any desired number of faucets located at any desired places.

It will also be understood that the details of the construction may be varied without departing from my invention.

l claim as my invention:

1. The combination, with a heater and l boiler, of a pipe leading from the heater to the boiler, a pipe l9 leading from the top of the boiler, a pipe 8 leading into the heater, a pipe 15 having one end connected to said pipe 8 and connected at a point intermediate to its ends to said pipe 9 a pipe 16 connected to the other end of said pipe 15 and a faucet provided in said pipe 16, a valve located in said pipe 15 between its points of connection with said pipes 8 and 9 and a piston connected with said valve and located between said pipe 9 and said faucet and said piston normally allowing said valve to remain operi by gravity and permit circulation through said pipe 15 and adapted to close said valve and shut off said circulation when said faucet 1S Open.

2. The combination, with a heater and boiler, of a pipe leading from the top of said boiler, a 'pipe' leading from said heater into said boiler, a pipe leading from said heater and communicating with the pipe leading from the top of said boiler, a faucet connected with said ipes, a valve interposed between the pipe 1leading from said heater and the pipe leading from the top of the boiler and normally opened by gravity, a faucet having a pipe connection with the pipes leading from said heater and from the top of said boiler, and a piston located between said faucet and the ipe leading from the top of said boiler and) connected with said valve and adapted to automatically close said valve when said faucet is opened.

3. The combination, with a heater and boiler, of the pipe leading from the heater to the boiler, a pipe 9 leading from the top of the boiler, a pipe 8, a pipe 15 connected with said pipes 8 and 9, a faucet connected with said pipe 15, a valve 17 located in said pipe 15 on one side of said pipe 9, a piston located on the other side of said pipe 9, and connected with said valve and comprisingadisk and a cylinder and having a series of holes therein, said valve 17 being normally open by gravity and the holes in said cylinder being normally closed to prevent assage of the water therethrough and sai disk and cylinder being raised to expose the holes in said cylinder and o en them to the assage of the water and c ose said valve w en the faucet is open, substantially as described.

In witness whereof, l have hereunto set my hand this 19 day of March 1906.
